This chapter focuses on internal developments in the border regions and the positive appeal of the Party's policies. These policies took the form of what later became known as the Yan'an model. The first aim of the Yan'an model, therefore, was to improve their quality in a process known as 'rectification'. In the rectification movement of 1942, leaders learned how to apply Marxist-Leninist theory to their work situation. The crisis in the border regions in 1942 revealed a defective local leadership. One of the primary aims of the rectification movement, which was centred on 27 documents, was to create a new leadership type—the 'cadre'. The ideal cadre operated within a network of human solidarity but was committed to change. The ideal cadre was preferably to be young. The cadre was required to tread the narrow path between 'commandism' and 'tailism'.
